DPNS_CREAT(3)						      DPNS Library Functions						     DPNS_CREAT(3)

NAME

       dpns_creat - create a new DPNS file or reset it in the name server

SYNOPSIS

       #include <sys/types.h>
       #include "dpns_api.h"

       int dpns_creat (const char *path, mode_t mode)

       int dpns_creatx (const char *path, mode_t mode, struct dpns_fileid *file_uniqueid)

DESCRIPTION

       dpns_creat creates a new DPNS file or resets it in the name server.

       If the file exists, the length is truncated to 0 and the mode and owner are unchanged.

       If  the file does not exist yet, an entry is created in the name server database and the file's owner ID is set to the effective user ID of
       the requestor.  The group ID of the file is set to the effective group ID of the requestor or is taken from the	parent	directory  if  the
       latter has the S_ISGID bit set.

       The  access permission bits for the file are taken from mode, then all bits set in the requestor's file mode creation mask are cleared (see
       dpns_umask(3)).

       dpns_creatx behaves in the same way and returns the file unique id (name server hostname and file id).

       path   specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname.

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

       ENOENT	    A component of path prefix does not exist or path is a null pathname.

       EACCES	    Search permission is denied on a component of the path prefix or the file does not exist and write permission  on  the  parent
		    directory is denied or the file exists and write permission on the file itself is denied.

       EFAULT	    path or file_uniqueid is a NULL pointer.

       EEXIST	    File exists already and has replicas.

       ENOTDIR	    A component of path prefix is not a directory.

       EISDIR	    path is an existing directory.

       EINVAL	    The fileclass in the parent directory is zero.

       ENOSPC	    The name server database is full.

       ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.

DPNS_SETFSIZE(3)					      DPNS Library Functions						  DPNS_SETFSIZE(3)

NAME

       dpns_setfsize - set filesize for a regular file; set also last modification time to the current time

SYNOPSIS

       #include <sys/types.h>
       #include "dpns_api.h"

       int dpns_setfsize (const char *path, struct dpns_fileid *file_uniqueid, u_signed64 filesize)

       int dpns_setfsizec (const char *path, struct dpns_fileid *file_uniqueid, u_signed64 filesize, const char *csumtype, char *csumvalue)

DESCRIPTION

       dpns_setfsize  sets the filesize for a regular file; set also the last modification time to the current time.  This function should only be
       called by the stager after the last write operation has been performed on the file.  The  file  can  be	identified  by	path  name  or	by
       file_uniqueid.  If both are specified, file_uniqueid is used.

       path   specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname.

       csumtype
	      specifies the type of checksum. Valid types are:

	      CS     standard 32 bits checksum

	      AD     Adler 32 bits checksum

	      MD     MD5 128 bits checksum

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

       ENOENT	    A component of path prefix does not exist or path is a null pathname.

       EACCES	    Search  permission	is denied on a component of the path prefix or the caller effective user ID does not match the owner ID of
		    the file or write permission on the file itself is denied.

       EFAULT	    path and file_uniqueid are NULL pointers.

       ENOTDIR	    A component of path prefix is not a directory.

       EISDIR	    The file is not a regular file.

       EINVAL	    The length of the csumtype exceeds 2 or csumtype is an unknown type or the length of the csumvalue exceeds 32.

       ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.
